What is the proper way to report this calculation ?

17.34 / 3.45?

• 5.026 because the 17.34 has the most sigfigs

• 5.03 because the 3.45 has the fewest sigfigs

• 5.026087 because you need the most decimal places for accuracy

• 5 because you should round the final answer to the nearest whole number
